The measure of one angle of a triangle is 115°. The other two angles are congruent. What is the measure of each angle?
1 answer:
The sum of the angles of the triangle is equal to 180°.
Let x be the measure of the each of the two angles. The equation that would best represent and relate the given measures of the angle is,
180 = x + x + 115
Group all variables and constants in each side of the equation.
180 - 115 = 2x
Simplifying,
65 = 2x
Divide the equation by 2,
32.5 = x
The value of x is equal to 32.5°.
Hence, the answer is the last choice.

Answer:
24
Explanation:
here,
BD=BC
BD=5x-26
BC=2x+1
AC=43
AB=?
now,
BD=BC
or, 5x-26=2x+1
or, 5x-2x=1+26
or, 3x=27
or, x=9
replacing x,
BC=2x+1
=2*9+1
=19
then,
AC=AB+BC
or, 43= AB+19
or, 43-19=AB
or, 24=AB
